ok i just lifted tank up to c was there any kinked lines etc . i also gave the carbs a tap to c if its a stuck float etc . the drips become quicker when engine is running . i cannot drive the bike with petrol dripping nxt to exhaust.

One of the float valves is leaking in one of the carbs. Problem being if one is leaking the others may follow.

Remove carbs and clean the float chambers and float valves on all 4 minimum.

Its worse when the engine runs due to thr automatic fuel tap/solenoid. When the engine is off so is the fuel.

Too right go back. They have caused the problem.

Dont accept any "well it was fine when we had it ", crap either.

right i took petrol cap off cleaned everything blew up each hose to make sure there not blocked then fit cap back on . started up the bike let it idle for a wile and still a bit of a drip of petrol comeing from overflow ?? next i added a shot of redex and drained the four carbs then started the bike n let it idle . repeated this 3 times and i think the petrol leak has stoped . will check again soon just to b sure !

You block that pipe and i'll block your posts.

That would be singularily the silliest thing i have heard so far. You do realise you have several gallons of what is basically an explosive liquid directly above a high energy ignition source, a couple of hydraulic lines and a fucking great high energy heat sourse. And inconveniently in very close proximity to your self.

In short block that pipe and you are potentially riding a bomb, you may cause vapour locks, fluid to go where its not ment to, bad just bad stuff.

Language can be harsh on here but if you do that you deserve it. It needs fixing. Period.

Your fuel cap is leaking. Or you havent been very carefull when you filled it up.

My tdr stinks of fuel if you park it in the sun. Tank and fuel heat up and the pressure has to go somewhere. Ie out the breather.

Are ya talkin about the Cap where ya fill her up with fuel?????,,,,, is it that pipe that is dripping fuel???

Open the cap and leave it open,,,,,start the bike an let run for a while,,,,see if the fuel drip stops.

I still think the people that fitted your restrictor have caused the problem.

The restrictor is 4 big washers with small holes in them. They are fitted to each of the carbs,,inside the inlet rubbers.

What happens i think is,,,,,, the holes in the restrictor washers are so much smaller than origional that it causes back pressure. This pressure cant go through the carbs and engine like it used to,,,, yet it has to go somewhere so mabey it gets forced back up into your tank. Then any movement of the bike will cause fuel to be forced out the overflow pipe.

At a guess this may be your prob.
